RESTAURANT E m s qT Ralph H; Hill, Flint, Mich. Application October 14, 194%; sei ial No fl'ifl lfigi 5 Claims.

This invention relates to. restaurant dining fixtures and more particularly to restaurant table and chair equipment of the ventilated type.

A main object of the invention is to provide a novel and improved restaurant table and chair unit which is simple in construction, easy to install, and which provides efficient ventilation and improved eatingcomfortfor a person using the unit.

A.. further object of the invention is to provide an improved'restaurant dining. unit and a method of ventilating the unit so that stale odors and foul air will be'carried away from the dining unit at all times, and fresh air will be continuously furnishedthereto.

A still further obj ect of the invention is to provide an improved combination counter and seat unit for restaurants and the like which is inexpensive to manufacture, versatile in the manner in which it may be connected and arranged with respect to like units, and provided with built in ventilating means .so that the air adjacent a person seated at the unit may be circulated to remove stale air and unpleasant odors and to replenish the supply of fresh air at the unit.

Further objectsand advantages of the invention will. become apparent from the following description andfclaims, and from the accompany? ing drawings wherein;

The exhaust ducts 20-=of the joined subassemblies are connected togetherat 23 to a common d'uct 24 which in turn is connected to a main-exhaust-duct'-25.- A suction fan 25 is provided in main duct 25 -to create the required draft therein.

Thetopof each. table section I5 is provided :a'djacent the transverseplane of the joining flanges I 8 I'd-thereof with afreshv air discharge grille. 21

duct 33 contains an intake blower .fan 34 adaptedto drawinto the main duct 33 th required;

amount of freshair to be furnished to the various booth fresh air discharge grilles.

In operation, stale;.air is exhausted from the interior of the booths through the intake gril-lesr l9 and 2l-and the respective exhaust ducts I 8',

2 2, 2c and-24*to the main exhaust-duct-25r At the same time, fresh air is furnished to them terior of the booths from the main; supply duct 33 through the respective feedducts 32-, 29 and :28 to the fresh air registers 30 and 21: Inthis' manner, theiair adjacent eachseat- TZ is kept fresh and all stale air and disagreeable odor's' adjustable forwardly and rearwardly with re-' spect to said post member. Secured to the bottom of each portion 35 is a flanged bar 31 slidably received in a channel member 38 secured to the top of the associated post member 36, the sliding fit of bar 31 in channel member 38 permitting the aforesaid adjustment. A wing bolt 39 extends through a slot in channel member 38 and is threaded into the bar 31, whereby the top seat portion 35 may be locked in a horizontally adjusted position. Post member 36 is telescopically received in a vertical sleeve member 40 secured to the base section I! and may be secured in a vertically adjusted position in said sleeve member by a wing bolt 4| threaded through the sleeve member 40 and engaging the post member.

In the arrangement shown in Figures 5 and 6, individual subassemblies each comprising a table section [5 mounted on a hollow floor section I? are secured together in an end-wise arrangement to form a counter. on the joined floor sections l1 midway between the intake grilles l9, IQ of adjacent sections, as shown in Figure 5. The individual subassemblies are each provided with hollow vertical column members 42 enclosing the exhaust and feed ducts l8 and 28. Although base stale air exhaust registers and conduits such as are shown at 2| and 22 in the embodiment of Figures 1 to 4 are not shown in the embodiment of Figures 5 and 6, they may be employed, if desired, in the same manner as in the embodiment of the invention previously described.

By connecting two of the individual subassemblies shown in Figures 5 and 6 back to back. a dining table and chair unit may be constructed similar to that shown in Figures 1 to 4 but without the side booth-defining vertical walls l4, Id.

The table top sections and floor sections may also be made with arcuate front and rear edge contours so that counters of circular or other arcuate shapes may be formed by connecting individual subassemblies together in endwise fashion.

Although certain specific embodiments of ventilated dining fixtures have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
